Saint-Gobain Meldin® 1003 Thermoplastic Bearing Material
Categories: Polymer; Thermoplastic; Polyphenylene Sulfide (PPS)

Material Notes: Meldin 1003 components offer the highest level of strength and rigidity for this product family. They maintain high chemical, tensile, and flexural properties even at elevated temperatures.

Meldin® 1000 series components are used in appliance applications due to their superior wear life and ability to operate without the need for any oils or lubricants. For scroll tip seal applications, Meldin® 1000 series materials provide some parts with superior wear resistance properties, and superior deformation properties over those of standard PTFE scroll tip seals. In vehicle systems such as transmission bearings or thrust washers, as well as fuel pump bearings, Meldin® 1000 series materials provide performance superior to metallic components. The Meldin 1000 series materials' wear resistance, coupled with their excellent chemical resistance, make them ideal materials for vehicle system components.
